I have just upgraded to UCS 4.2. Pre the upgrade I had a happy Kopano install with Z-Push for Kopano working well also.
After upgrade, Z-Push ceased working. So I uninstalled it successfully from the UMC AppCenter with a view to reinstalling it. When installing via the AppCenter, the “running tests for installed applications” message displays for some minutes prior to an error dialogue stating “Internal Server Error”.
The only trace I can find in logs is from the management-console-module-appcenter.log:-
09.04.17 10:56:34.425 MODULE ( PROCESS ) : Finished dry_run for z-push-kopano on localhost 09.04.17 10:56:34.426 MODULE ( PROCESS ) : Problems encountered or confirmation required. Removing component z-push-kopano_20170308162400
Trying a command-line install with “univention-install z-push-kopano” results in:-
Package z-push-kopano is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source
I have read that Kopano can be updated from an alternate Kopano repo on UCS 4.2, but would rather try to get this issue sorted without maybe complicating things with additional repos at this point. Any guidance/help/advice would be greatly appreciated.
